Generic diagram: wall-mounted heat pump, indoor and outdoor units

In summer, the outdoor unit rejects the house's heat outside.

Generic illustration of this type of installation, not a survey of this job site. Tap a number.

  1. Mounted level on a wall plate, high enough for the air to reach the whole room, with enough space around it to slide the filters out easily.

  2. The refrigerant lines, the communication cable and the drain go through the wall in a single opening, sealed against water, cold air and insects.

  3. Two insulated copper pipes connect the two units. Outside, a line cover can protect them from sun, knocks and weather.

  4. A shut-off switch near the outdoor unit isolates it safely for service. It must stay accessible at all times.

  5. The compressor and the fan. In heating mode it captures heat from the outdoor air, even in winter, and moves it inside.

  6. On the ground or on the wall, it keeps the unit above accumulated snow. The unit stays clear and defrost water can drain away.

  7. The fan needs to blow freely. Storage, a fence or a wall too close, and efficiency drops while noise goes up.

On the South Shore, in Saint-Bruno , single-family homes often present a very specific HVAC challenge: achieving stable air conditioning in the summer while enjoying efficient heating during the shoulder seasons (and for as long as possible in winter), without increasing electricity bills. This is precisely the objective of this installation by AirGreen , using a Fujitsu AIRSTAGE wall-mounted heat pump with R-32 refrigerant.

Although the photo mainly shows the outdoor unit, the overall setup clearly corresponds to a mini-split system (wall-mounted indoor unit + outdoor condenser). This is a perfect solution when you want targeted comfort (living room, open-plan area, upstairs, master bedroom) without the need for extensive ductwork.


The system installed: Fujitsu wall-mounted heat pump (AIRSTAGE R-32)

Since the brand name is provided manually, it is indeed a Fujitsu . The visible label also indicates AIRSTAGE and R-32 , which points to a recent, high-performance generation better aligned with new refrigerant standards.

To remain consistent with the Fujitsu R-32 range used in residential settings, a typical and realistic model in this context is a Fujitsu Orion XLTH (KZAH R-32) — a series appreciated for its ability to maintain good performance when the outside temperature drops (an important point in Quebec).


What the outdoor installation reveals (and why it matters)

1) Elevated unit on metal support: a winning choice in Quebec

The outdoor unit is placed on a raised support installed on a concrete base. This approach is particularly relevant in our climate, as it helps to:

  • to limit the impact of snow and ice accumulation on the ground,

  • improve drainage around the device,

  • reduce the risk of obstructed airflow in winter,

  • facilitate maintenance (easier access, quick visual inspection).

It's a detail that seems "simple", but it has a huge impact on reliability season after season.

2) Clearances and positioning near the facade

The unit is installed close to the wall, but with sufficient clearance on the supply/exhaust side. The proximity of a window is also noted: in these cases, particular attention is paid to:

  • the fan's orientation,

  • vibration reduction,

  • and the positioning in order to preserve acoustic comfort inside.

3) Environmental management: vegetation and obstacles

We see ornamental grasses and a flowerbed nearby. In a single-family home, this is very common, and it implies a golden rule: keep the unit clear to prevent vegetation from reducing airflow and accelerating coil fouling. At AirGreen, we install cleanly, then clearly explain the distances to maintain to protect performance.

4) Clean, stable installation ready for the seasons

The support is level, the unit is properly leveled, and the installation on a solid slab provides a stable base. This stability contributes to:

  • reduce resonance noise,

  • limit premature wear,

  • to improve the customer experience on a daily basis.


Why a Fujitsu wall-mounted unit is ideal for a home in Saint-Bruno

In this type of property, a mini-split system is often chosen because:

  • to effectively air-condition an open area (living room/kitchen),

  • to improve the comfort of a floor that overheats in the summer,

  • reduce the use of baseboards in autumn and spring,

  • to obtain precise control piece by piece (depending on the area targeted).

A well-sized Fujitsu AIRSTAGE stands out because of:

  • stable inverter modulation (fewer "start/stop" cycles),

  • more consistent comfort

  • excellent mid-season yield,

  • It generally operates very quietly when the installation is done correctly.


What we systematically monitor at AirGreen (the real difference)

Even an excellent machine won't reach its full potential if certain aspects are overlooked. For this type of project, we apply our AirGreen standards:

  • Route of refrigeration lines : logical, protected, with clean finishes.

  • Rigorous vacuuming : essential for the longevity of the compressor.

  • Leak testing : preventing losses and maintaining performance.

  • Condensate management : reliable drainage, adequate slope, prevention of backflow.

  • Clearances : for air, maintenance, noise… and durability.

  • Stability / anti-vibration : to protect the structure and acoustic comfort.


Maintenance advice for this type of installation (single-family home)

To maintain optimal performance year after year:

To be done regularly

  • Keep the outdoor unit clear (leaves, branches, grass, snow).

  • Visually check that no object is blocking airflow.

To be done periodically

  • Cleaning of the coils (if necessary, especially if in a vegetated environment).

  • Complete inspection (electrical connection, supports, general condition, operating parameters).

Simple and well-planned maintenance prevents performance drops and extends the system's lifespan.


Conclusion: a Fujitsu installation designed for comfort and the Quebec climate

This installation in Saint-Bruno highlights an approach we favour at AirGreen: choosing a Fujitsu AIRSTAGE R-32 wall-mounted heat pump adapted to Quebec, then installing it in a durable manner — elevated, stable, well clear and properly integrated into the exterior landscaping.

The result: superior comfort in summer, better efficiency in mid-season, and an installation ready to face our winters.

    Frequently asked questions

    What people ask us about this kind of work

    12 questions
    Does a wall-mounted heat pump heat in winter?
    Yes, it heats and cools. Its capacity drops in very cold weather; the operating range depends on the model and is listed on its spec sheet.
    Wall-mounted or multi-zone: how do I choose?
    One wall head and one condenser outside: the direct solution for a room or an open area. For two to five rooms, a multi-zone puts one head in each room on a single condenser.
    Where does the outdoor unit go?
    Where it stays above the snow, clear and accessible, away from walkways. We decide it with you during the estimate.
    Are there grants?
    Depending on the model and your situation, assistance programs may apply, including Hydro-Québec's LogisVert. AirGreen checks the model number before quoting an amount. See the grants.
    Do I need a permit?
    Rules vary from city to city: location, distances, noise. See permits and by-laws, and we check for your address.
    How cold can it heat?
    It depends on the model. According to Hydro-Québec, newer models work down to a temperature between −15 °C and −25 °C, and some cold-climate models are certified lower. The minimum temperature is on each unit's spec sheet.
    How much can I save?
    Hydro-Québec says a heat pump can be up to three times more efficient than baseboards for heating in the colder months. The result depends on the house, the climate and how it is used.
    How is the LogisVert assistance calculated?
    For ENERGY STAR cold-climate certified heat pumps, Hydro-Québec lists assistance of $120 per 1,000 BTU/h of heating capacity at −8 °C. AirGreen checks the exact model before quoting an amount; only Hydro-Québec confirms the assistance granted. See the grants.
    Is it noisy?
    The sound level depends on the model and is listed in decibels on each unit's spec sheet. Location matters too: when possible, we avoid putting the outdoor unit under a bedroom window.
    The outdoor unit is covered in ice: is that normal?
    Some frost is: the unit runs defrost cycles. Never hit the ice. If the unit stays iced up or stops heating, call us.
    Does AirGreen hold the required licences?
    Yes. AirGreen holds RBQ licence 5645-9605-01, subclasses 15.8 Ventilation, 15.10 Refrigeration and 16 Electricity.
